Abstract
A LED controller for an LED pixel array includes an image frame buffer to receive image data and a standby image buffer connected to the image frame buffer to hold a standby image. A command and control module connected is configured to substitute the standby image in the standby image buffer for the image in the image frame buffer when image data is unavailable.
Claims20
A LED controller for an LED pixel array, the LED controller comprising:
- a drive module configured to drive the LED pixel array;
- an image frame buffer configured to receive image data;
- a standby image buffer connected in series with the image frame buffer to the drive module, the standby image buffer configured to hold a standby image;
- and
- a command and control module connected to both the image frame buffer and the standby image buffer, the command and control module configured to direct the standby image in the standby image buffer to the image frame buffer in response to determining that the image data is unavailable.
